1: Pressure feed-
back exceed pump
limit
Actual pressure exceeding
[F4.16] (pump maximum
pressure)
1. Set pressure to a lower val-
ue
2. Check if the wiring is prop-
erly connected for pressure
feedback transmission
3. Increase [F4.16]
2: Pressure sensor
error
1. The motor negative speed
exceeding [F4.06] with dura-
tion time exceeding [F4.07]
2. The slow decrease of ac-
tual pressure after the shut-
down
1. Check if pressure trans-
ducer can work properly. In-
crease the setting of F4.06,
F4.07, F4.08 and F4.09
2. Check if pressure trans-
ducer can work properly. In-
crease the setting of F4.10
and F4.11
3: Parameter setting
error
Parameter setting repetition Check if parameter settings
are in conflict
4: Oil filter error
Oil filter full
Clean or replace filter
5: Oil level error
Oil level too low
Refill oil
6: Oil temperature
error
Oil temperature reached
Reduce hydraulic loses or en-
hance oil cooling
7: Oil change error Operation time exceeds oil
life time
Change oil and reset opera-
tion timer F4.54
8: Oil level or tem-
perature error
No warning signal for oil level
and temperature available, or
both are active.
1. Check warning signal / sen-
sor
2. Same solution as oil level /
temperature error
9: Pump thermal
protection error
Pump speed is lower than re-
quired for pump cooling
F4.36
Increase system minimum
speed
